Abstract: A power management method is adapted for a computer system that includes a CPU, a control unit, a BIOS and multiple PSUs. When one PSU operates abnormally, it sends an alert signal that is in an alert state to the control unit, and the control unit causes the CPU to operate under a predefined lowest power consumption limit. The control unit computes an updated power consumption limit, and notifies the BIOS to write the updated power consumption limit into a model-specific register of the CPU, so as to make the CPU operate under the updated power consumption limit.
